Computers nowadays are more and more widely used in education. Hence, some people claim that teachers are no longer playing important roles in the classroom. I completely agree with this statement. Although teacher may be more emotional than computers, the later actually far outdoes in educating students, for the following three reasons.

　　First, it is an undoubted fact that computer are more likely to provide sufficient information to students. Neither a well trained graduate from education institute nor an experienced teacher can offer more knowledge than an advanced computer.Human brain is more suitable for creative activities, but not in conveying information. As a result of the rapid development in technology, the computer’s capacity of containing information will become much stronger.

　　Second, computers are more efficient in educating students than teachers, not only because they will merely make mistakes, but also due to that the will not feel worn out after a long time of work. It goes without saying that teachers are some times complained to transfer mistaken messages to students. And the latter, lack of enough related knowledge, finally become the victims of such mistakes. Further more, as they were so tired after a whole day working, teachers are often slow in reaction while asked questions by students. Computers, which can never effected by emotional factors, have no such disadvantages.

　　Last but not least, children are becoming more and more familiar with computers while they are being taught by this new technology. It’s widely accepted that computer has become an essential tool for our daily life. Children could learn how to master it better by the process of being educated by it rather than taking an intentional class presented by a teacher. Classroom, as everybody believes, is a place where students learn knowledge and skills, both academic and practical. So it should be the duty for school to prepare students for the computer-oriented society

　　All in all, although teachers still contribute to education, we can’t turn a blind eye to the fact that they are not important any more compared to another kind of tutors-computers.
